1390 - Four Divisors\. Medium Given an integer array `nums`, return _the sum of divisors of the integers in that array that have exactly four divisors_. If there is no such integer in the array, return `0`. **Example 1:** **Input:** nums = [21,4,7] **Output:** 32 **Explanation:** 21 has 4 divisors: 1, 3, 7, 21 4 has 3 divisors: 1, 2, 4 7 has 2 divisors: 1, 7 The answer is the sum of divisors of 21 only. **Example 2:** **Input:** nums = [21,21] **Output:** 64 **Example 3:** **Input:** nums = [1,2,3,4,5] **Output:** 0 **Constraints:** *1 <= nums.length <= 104*1 <= nums[i] <= 105
